,Q1 CRITICALLY EVALUATE IMPLANT TREATMENT PLANS BASED ON COMPREHENSIVE
DIAGNOSTIC DATA
A CBCT reveals a 4.0 mm wide alveolar ridge in the posterior mandible. Which of
the following is the most critical factor when considering guided bone
regeneration (GBR) versus ridge splitting for implant placement?
A. The patient's platelet count
B. The presence of at least 2 mm of bone above the inferior alveolar nerve CORRECT
C. The keratinized tissue width
D. The planned implant diameter
RATIONALE: The critical factor is the vertical bone height above the inferior alveolar nerve, as it
determines whether ridge splitting (which requires a minimum height) or GBR (which can
augment both width and height) is feasible. Platelet count and keratinized tissue are less critical.
Implant diameter can be adjusted but is not the primary determinant.
Q2 CRITICALLY EVALUATE IMPLANT TREATMENT PLANS BASED ON COMPREHENSIVE
DIAGNOSTIC DATA
Which of the following best explains the higher long-term survival of implants
placed in the anterior mandible compared to the posterior maxilla?
A. Greater cortical bone density in the mandible CORRECT
B. Lower occlusal forces in the anterior region
C. Higher vascularity of the mandibular bone
D. Shorter implant lengths used in the mandible
RATIONALE: The anterior mandible typically has dense cortical bone (Type I/II), which provides
better primary stability and osseointegration. The posterior maxilla often has poor bone quality
(Type III/IV) and lower density, leading to higher failure rates. Occlusal forces are not lower in the
anterior mandible; in fact, they can be high. Vascularity is not the primary factor.

,Q3 CRITICALLY EVALUATE IMPLANT TREATMENT PLANS BASED ON COMPREHENSIVE
DIAGNOSTIC DATA
A patient presents with peri-implantitis and a 5 mm probing depth with bleeding
on probing. Radiographs show 30% bone loss. Which of the following is the most
appropriate initial non-surgical treatment?
A. Systemic antibiotics alone
B. Mechanical debridement with titanium or plastic instruments CORRECT
C. Immediate explantation
D. Open flap debridement with bone grafting
RATIONALE: Initial non-surgical therapy for peri-implantitis includes mechanical debridement to
remove biofilm and calculus. Using titanium or plastic instruments minimizes damage to the
implant surface. Systemic antibiotics are adjunctive, not primary. Explantation is reserved for
advanced cases. Surgical intervention is considered after non-surgical therapy fails.
Q4 CRITICALLY EVALUATE IMPLANT TREATMENT PLANS BASED ON COMPREHENSIVE
DIAGNOSTIC DATA
A patient is to receive a single implant in the esthetic zone. Which of the following
factors is the most critical predictor of achieving a stable peri-implant soft tissue
contour?
A. Implant platform diameter
B. The thickness of the buccal bone plate CORRECT
C. The type of abutment material
D. The depth of implant placement
RATIONALE: A thick buccal bone plate (2 mm) is essential for maintaining the peri-implant soft
tissue and preventing recession. A thin buccal plate often resorbs, leading to soft tissue collapse.
Implant platform diameter and abutment material are secondary. Depth of placement affects
emergence profile but not as critically as bone thickness.

, Q5 CRITICALLY EVALUATE IMPLANT TREATMENT PLANS BASED ON COMPREHENSIVE
DIAGNOSTIC DATA
Which of the following is the most appropriate method to verify the accuracy of a
digital implant impression?
A. Use of a verification jig with acrylic resin
B. Comparing the digital scan to a conventional polyether impression CORRECT
C. Using a high-resolution intraoral scanner
D. Radiographic evaluation with a periapical film
RATIONALE: To verify accuracy, the digital scan should be compared to a reference standard,
such as a conventional impression, to assess discrepancies. Verification jigs are used for multiple
implants but do not verify the scan itself. High-resolution scanners are important but do not verify
accuracy. Radiographs do not provide 3D accuracy of the impression.
Q6 CRITICALLY EVALUATE IMPLANT TREATMENT PLANS BASED ON COMPREHENSIVE
DIAGNOSTIC DATA
For a full-arch implant-supported fixed prosthesis, which of the following is the
primary advantage of using a titanium framework over a cobalt-chromium (Co-Cr)
framework?
A. Lower cost
B. Higher biocompatibility CORRECT
C. Greater rigidity
D. Lighter weight
RATIONALE: Titanium is known for superior biocompatibility, reducing the risk of allergic
reactions and corrosion. Co-Cr is also used but may cause hypersensitivity in some patients.
Titanium is not necessarily cheaper or lighter; Co-Cr can be lighter. Rigidity is similar, but
biocompatibility is the primary advantage.
